Take it back before you mount it. The new buck masters are not the same scope as the old BM. Read reviews from 2015 only. lots of feature and quality differences. Makes sense with the strong dollar that they would go cheaper. Assuming you are fairly new to this based on questions. I approach it this way ,why take a $400+ gun and put $100 glass on it? The gun will only shoot as good as the glass right?. You would be better off going to eBay and buying a 1980's varix III for that $100. Or an old red field wide field 4x fixed for even less.
